invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to threshing-ma chines, and has for its object toimprove the same in the several particulars hereinafter noted.

The invention consists of the novel devices and combinations of deviceshereinafter described, and defined in the claims.

In the accompanying drawings, which illustrate my invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation withsome parts broken away and some parts shown in sections and illustratingmy invention applied to a threshing-machine having a pneumatic stacker.Fig. 2 is a horizontal section on the line 90 90 of Fig. 1, some partsbeing broken away. Fig. 3 is a horizontal section on the line 90 of Fig.1., some parts being broken away. Fig. 4 is a detail in rear elevation,showing substantially the same parts that are shown in detail in Fig. 3;and Fig. 5 is a vertical section on the line a x of Fig. 3.

The numeral 1 indicates the case of the threshing-machine,whichthreshing-machine, except as hereinafter particularly noted, may be ofstandard construction.

The numeral 2 indicates diagrammatically one of the rear wheels of themachine.

The numeral 3 indicates the vibrating sieveshoe, which is provided withshoes 4 and 5 and with a discharge-hopper 6 at its rear end. Thedischarge hopper 6 discharges into a transversely-extended grain-spout 7of the usual construction. Depending from the rear edge of the sieve 5is a vertical partition 8, that is rigidly secured to the sides of theshoe 3 and terminates at its lower edge slightly above the bottom of thehopper 6. The compartment 6 is thus formed in the rear end of thevibrating shoe 3, which oompartment extends completely across said shoe.Extending over the open top of the compartment 6* of the hopper 6 is acoarse sieve 9, which is rigidly secured to a frame 10, having adepending flange that is adj ustably secured to the partition 8, asshown, by means of short nutted bolts 11. This sieve 9-may therefore beset in different vertical adjustments with respect to the sieve 5;

A vibrating grain-pan 12, which may be of usualconstruction and mountedand driven in the usual way, is so related to the sieves 5 and 9 that itwill discharge chaff, light dust, and more or less grain directly ontothe said two sieves.

By means of the usual separator-fan (not shownl a blast of air will beblown through the shoe 3 in the direction indicated by the arrow markedthereon in Fig. 1, and this blast will strike the partition 8 and beforced upward through the perforations of the coarse sieve 5 and willcarry off the dust and light particles and will frequently also carryofi more or less of the good grain. Such good grain and some of thebroken straw and like foreign particles will fall from the blast ontothe supplemental sieve 9, and such grain will freely fall through theperforations of the.

said sieve 9 and will fall under the action of gravity into the dead-aircompartment 6 of the hopper 6. As is evident, no perceptible amount ofthe air-blast will be passed into the said so-called dead-air chamber6*, hence will not impede the precipitation into the said compartment.From what has been said it will be understood that the addition to thesieve-shoe is in the nature of a grain-saving device, the intentionbeing to catch and reclaim grain which is blown from the separator,together with the straw and other foreign materials.

Of the parts of the pneumatic stacker the numeral 12 indicates thefancase, and the numerals 14 and 15 indicate sections of thedischarge-stack, said sections 15 beinga movable section which ispivoted at 16 to the discharge-neck of said fan-case. This pivotedstacker-section when dropped downward, as shown by dotted lines in Fig.1, affords access to the interior of the stack and permits the removalof any straw which may have been caught within and clogged the stack.When the hinged section 15 is turned upward into an operative position,as shown by full lines in Fig. 1, its upper end registers with the lowerend of the stack-sections 14, which stack-sections 14 of the fan-case 13are secured to a supplemental framework 17, rigidly attached to theseparator-case 1, Normally the upper end of the stack-sections 15 issecured in its operative position by a lockring or yoke 18, thatsurrounds the alined and abutting ends of said two stack-sections, andis pivoted for vertical movements 'at 19." To the rearvertically-movable portion of the lock-ring 18 is pivotally attached anoperating-lever 20, which lever in turn is pivoted to the supplementalframe 17 at 21 and cooperates with a notched latch-bar 22, by means ofwhich it is adapted to be set in either of two positions, When thelock-ring 18 is raised, it is moved clear of the upper end of the hingestack-sections 15, and said stack-sections may then be dropped downwardinto an inoperative position, as already stated. When the said lock-ringis lowered, it engages and securely holds the said hinge stacksectionsin its operative position, (shown by full lines in the drawings.) Thisdevice affords means for quickly and easily cleaning out a stack whichhas been clogged with straw.

The improved features of the construction described add but little tothe cost of a machine and greatly improve the same. It will of course beunderstood the features of construction described are capable ofmodifica- 'overlyingsaiddead-air chamber and inde pendently adjustablewith respect to said shoe-sieve, substantially as described.

In a threshing-machine, the combination with a sieve-shoe 3provided with sieves 4 and 5, with a discharge-hopper 6, and with apartition 8, said partition affording a'deadair chamber 6 andterminating above the bottom of said discharge-hopper, of a vertically-adjustable sieve 9 overlying said deadair chamber 6, andindependently adjustable with respect to said sieves 4 and 5,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
